As far as your hand plane, I don't know what to say.    Mike</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A title=mfarrel2@tampabay.rr.com href="mailto:mfarrel2@tampabay.rr.com">Farrell</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Wednesday, February 20, 2008 1:29 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Hand Plane Chatter</DIV> <DIV><BR></DIV> <DIV><FONT face=Arial>Question for the wood chomping gurus out there.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>I have a hand plane that has a propensity to "chatter" in use. Picture of it is below. The reason the base looks as if it is curved is because it is curved. That's the whole deal with this plane - the base curvature is adjustable to any gentle curve - convex or concave. It's great for planing many wooden things found in piano bellies and jigs to make those things. But it can be a bear when the darn plane wants to chatter.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Obviously, the plane is not a 35 lb. forged steel heavyweight. It is a high quality German plane, but I think the adjustable base feature necessitates a lighter weight. I wonder if the chattering is simply related to it's light-weight design (relatively speaking - the plane is NOT really anything I would call light-weight).</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>The blade is sharp, the cap iron is mated nicely to the blade and adjusted about 1 mm from the blade edge. I think everything is in order. But the darn thing still chatters up a storm. Any ideas/suggestions?</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><IMG alt="" hspace=0 src="cid:015601c873f4$640c6ed0$2f01a8c0@MCO2376" align=baseline border=0></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>BTW, I am trying to plane a curved caul, so I can't use a flat plane.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Terry Farrell<BR>Farrell Piano</FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial><A href="http://www.farrellpiano.com">www.farrellpiano.com</A><BR><A href="mailto:terry@farrellpiano.com">terry@farrellpiano.com</A></FONT></DIV></BLOCKQUOTE></BODY></HTML>
